I The invention relates to that class of buck les known as slides andused for adjusting the length of straps, webbing, and the like, withoutpenetrating the material, and especially to such buckles having arelatively sliding intermediate bar, and theobjects of the invention areto provide a reversible buckle oft-heiaforesaid type and to provide theupper and lower bars and the sliding in termediate bar with associatingprojections and indentations extendingand lying along *the plane of thebuckle and capableof grip ping a strap crowded into spaced bightslaterally extending across the strap threaded '1 into the'buckle. l/Viththese and other'objects in View as may become apparent from the withindisclosures the invention consists not only of the particular formherein pointed out and illustrated in the drawing but readily admits ofcertain modifications within the scope of what hereinafter may beclaimed.

' The following is the description of an embodiment of the invention,reference being had to the accom anying d-rawingin which the Figure 1 isa ace view of the buckle; the

1 Figure 2 is a bottom View; and the Figure 3 is an end elevation.

Referring more particularly to the drawing. in which similar numbersrefer to similar parts, the buckle while illustrated as made of wire maybe stamped from sheet metal or made in any other desired manner, but asillustrated the buckle is made from two pieces of wire Of'WhlCh onepiece is formed into a rectangular shape with ends secured together byelectric welding or other means and thus providing a buckle frame havingthe upper bar 1, the lower bar 2, andthe end bars 3 and 4E, and theother piece of wire forming a bar 5 is provided at its extremitieswith'eyes 6 and 7 adapted to surround the endbars 3 and 4, respectively,to permit a relative movement of the bar 5 upon the buckle frame. Bothupper and lower bars 1' and 2 are flattened in the plane of the framesubstantially throughout their respective lengths, the inner edges ofthe flattened portions being provided with spaced recesses 8. Spacedportions of the bar 5 are also flattened in the plane of the frame toform spaced projections 9 extending in opposite directions andcapableofregistering well within the recesse's'8 of either of" the bars1 and 2 as the bar is a'dvan'cedfon the frame'to one or'the' other ofits two extreme lpositions.

uckle is adapted to recei've a strap (not illus trated) in the usualmanner andthat strain tending to move the bar 5 toeither extremeposition will cause certain of the projections 9 to bear againstthe'strap threaded within the buckle in the attempt of the pro- 'ectionsto enter certain ofthe recessesB' thus wedging spaced portions extendinglat It becomes apparent that the erally across the strap into therecesses where I the strap isheld by the continuedbearing of theprojections upon the strap solong as'thestrain is placedupon the bar *5.While the recessesS are illustrated as being provided by theprojections9 by the the bars 1 and 2, and

bar 5, yet the 'provisionsfor the recesses and} the projections may bereversed as between,

theIbars 1 and 2and'thebar5. The sliding bar 5 operable in the planeofthe frame'pro-- vides a'buckle"adapted tor'eceive a strap withoutregard to the relative position ofithe bucklethereto. 1

What I claim is I s '1. A slide buckle comprising a rectangular frame,the inner edge of one of the longer portions of the frame having spacedsquare recesses, and a cross-bar slidably mounted upon the ends of theframe and having spaced square projections within the plane of the framefor engagement within the recesses.

2. A slide buckle comprising a rectangular frame, the inner edges of thelonger portions of the frame having spaced square recesses, and across-bar slidably mounted upon the end portions of the frame and havingspaced square projections extending from the bar in opposite directionswithin the plane of the frame for engagement within the recesses towardwhich the bar is advanced.

3. A slide buckle comprising a substantially rectangular buckle framehaving parallel of the flattened portions being provided with spacedsquare recesses; and a'bar 'slidably mounted upon the endbars and havingflattened portions forming spaced square pro- 7 jections extending inopposite directions from the bar in the plane of the frame forengagement within the'recesses toward which the bar is advanced; j

L. A slide buckle comprising a rectangular 7 frame formed from a singlepiece ofwire, a 1O substantial portion ofthe upper and lower} bars ofthe'fra'me being flattened in the plane of the frame, the inner edges ofthe flattened portions being provided with spaced square} recesses, anda wire bar slidably mounted upon the end bars of the frameand being Iprovided with flattened portions forming spaced square projectionsextending in oppo'site directio'ns'irl the plane of the frame forengagement within thev recesses towar f Which the bar is advanced.

5. A slide buckle comprising arectangular frame having upper and lowerbars and end bars a cross-bar slidably mounted upon the end bars; andspaced recesses and spaced projections, the recesses being thecounterpart ofthe projections, for interfitting engagement and provided,(one by'the inner portions of the upper and lower bars and the otherby'the sliding bar within the plane of the frame.

6. A slide buckle comprisinga rectangular frame having end bars, andupper and lower bars flattened inthe plane of the frame; across-bar=slidab1y mounted upon the end;

bars; and spaced recessesiand spaced projections, the recessesbeingthecounterpart-of the projections, for interfitting engagement andprovided, one by the inner edges of the I flattened upper and lowerbarsand the other a 40 by the sliding bar within the plane of the frame. i
